    Rez. in: nfd 54(2003) H.8, S.497 (T. Mandl): "Gesetze der digitalen Anarchie - Hyperlinks im Internet entstehen als Ergebnis sozialer Prozesse und können auch als formaler Graph im Sinne der Mathematik interpretiert werden. Die Thematik Hyperlinks ist im Information Retrieval höchst aktuell, da Suchmaschinen die Link-Struktur bei der Berechnung ihrer Ergebnisse berücksichtigen. Algorithmen zur Bestimmung des "guten Rufs" einer Seite wie etwa PageRank von Google gewichten eine Seite höher, wenn viele links auf sie verweisen. Zu den neuesten Erkenntnissen über die Netzwerkstruktur des Internets liegen zwei sehr gut lesbare Bücher vor. Der Autor des ersten Buchs, der Wirtschaftswissenschaftler Huberman, ist Leiter einer Forschungsabteilung bei Hewlett Packard. Huberman beschreibt in seinem Buch zunächst die Geschichte des Internet als technologische Revolution und gelangt dann schnell zu dessen Evolution und den darin vorherrschenden Wahrscheinlichkeitsverteilungen. Oberraschenderweise treten im Internet häufig power-law Wahrscheinlichkeitsverteilungen auf, die der Zipf'schen Verteilung ähneln. Auf diese sehr ungleichen Aufteilungen etwa von eingehenden HypertextLinks oder Surfern pro Seite im Internet bezieht sich der Titel des Buchs. Diese immer wieder auftretenden Wahrscheinlichkeitsverteilungen scheinen geradezu ein Gesetz des Internet zu bilden. So gibt es z.B. viele Sites mit sehr wenigen Seiten und einige wenige mit Millionen von Seiten, manche Seiten werden selten besucht und andere ziehen einen Großteil des Internet-Verkehrs auf sich, auf die meisten Seiten verweisen sehr wenige Links während auf einige wenige populäre Seiten Millionen von Links zielen. Das vorletzte Kapitel widmen übrigens beide Autoren den Märkten im Internet. Spätestens hier werden die wirtschaftlichen Aspekte von Netzwerken deutlich. Beide Titel führen den Leser in die neue Forschung zur Struktur des Internet als Netzwerk und sind leicht lesbar. Beides sind wissenschaftliche Bücher, wenden sich aber auch an den interessierten Laien. Das Buch von Barabási ist etwas aktueller, plauderhafter, länger, umfassender und etwas populärwissenschaftlicher."

    Rez. in: CD Info. 2003, H.10, S.12: "Der Aufwand bei der Internet-Recherche hat sich mit guten Suchmaschinen wie Google verringert. Trotzdem verbringt der Computeranwender eine Menge Zeit mit dem Öffnen und Schließen von Webseiten, die er nie benötigt hätte. Wer die Arbeitsweise und die Möglichkeiten von Google kennt, kann die Suche besser eingrenzen und gelangt oft direkter zur gewünschten Homepage. Der Google Pocket Guide erläutert die Funktionsweise des am meisten verwendeten Suchtools, gibt Tipps zur optimalen Nutzung und liefert gleich einige konkrete Beispiele für deren Verwendung. Neben den Optionen der Erweiterten Suche widmet sich das kleine Taschenbuch auch der Syntax der Website, sodass die Befehle direkt in die Suchmaske eingegeben werden können. Auch Zusatz-Features wie die Bildersuche, der Webkatalog, die Newsgroup-Datenbank sowie der seit Kurzem auch in deutscher Sprache verfügbare News-Bereich werden behandelt. Der Google Pocket Guide erläutert kurz und bündig die wichtigsten Techniken und hilft Zeit und Aufwand zu sparen. Der brandneue Titel ist derzeit leider nur in Englisch verfügbar."

    Abstract
    Are we at a turning point in digital information? The expansion of the internet was unprecedented; search engines dealt with it in the only way possible - scan as much as they could and throw it all into an inverted index. But now search engines are beginning to experiment with deep web searching and attention to taxonomies, and the semantic web is demonstrating how much more can be done with a computer if you give it knowledge. What does this mean for the skills and focus of the information science (or sciences) community? Should information designers and information managers work more closely to create computer based information systems for more effective retrieval? Will information science become part of computer science and does the rise of the term informatics demonstrate the convergence of information science and information technology - a convergence that must surely develop in the years to come? Issues and questions such as these are reflected in this monograph, a collection of essays written by some of the most pre-eminent contributors to the discipline. These peer reviewed perspectives capture insights into advances in, and facets of, information science, a profession in transition. With an introduction from Jack Meadows the key papers are: Meeting the challenge, by Brian Vickery; The developing foundations of information science, by David Bawden; The last 50 years of knowledge organization, by Stella G Dextre Clarke; On the history of evaluation in IR, by Stephen Robertson; The information user, by Tom Wilson A; The sociological turn in information science, by Blaise Cronin; From chemical documentation to chemoinformatics, by Peter Willett; Health informatics, by Peter A Bath; Social informatics and sociotechnical research, by Elisabeth Davenport; The evolution of visual information retrieval, by Peter Enser; Information policies, by Elizabeth Orna; Disparity in professional qualifications and progress in information handling, by Barry Mahon; Electronic scholarly publishing and open access, by Charles Oppenheim; Social software: fun and games, or business tools? by Wendy A Warr; and, Bibliometrics to webometrics, by Mike Thelwall. This monograph previously appeared as a special issue of the "Journal of Information Science", published by Sage. Reproduced here as a monograph, this important collection of perspectives on a skill set in transition from a prestigious line-up of authors will now be available to information studies students worldwide and to all those working in the information science field.
